Construction Client Portal Builder: Progress, Variations and Payments in One Login

A construction client portal gives each client one login where they see their own build: progress photos by phase, drawings and certificates, stage payments and variations to approve. Mythex builds it from a description, with per-client access and a real database.

Who it's for

Builders and renovation contractors whose clients phone or message several times a week asking how things are going, and whose variations are agreed verbally on site and argued about at the end. Works for residential clients, developers and commercial clients alike.

What you can build

A phase timeline per project, from groundworks to snagging, with planned and actual dates
Progress photos posted by site managers from a phone, filed under the right phase
Drawings, building control sign-offs and warranties stored per project
Variations with a description and price that the client approves in the portal
Stage payment schedule with invoices and what has been paid
A staff area to see every project, post updates and reply to messages

Put variations in writing, in the portal

Most disputes on building jobs start with a change agreed on site: move the door, upgrade the tiles, add a socket. Weeks later nobody agrees what was said or what it cost. In the portal each variation is a record with a description, a price and an approve or reject button for the client, stamped with the date. The site team does not start the change until it shows as approved. At final account the list is already there, signed off.

Description, price and effect on the programme
Client approval with date recorded
Approved variations flow into the next invoice

Progress the client can see without ringing

Clients ring because they cannot see anything. If the site manager uploads four photos at the end of each week, tagged with the phase, the client has their answer before they reach for the phone. Ask for the photos to be shown on a timeline with the next milestone and its expected date. It also helps you: stage payment invoices can point to the photos that show the stage was reached.

Access rules to state in your prompt

Say clearly that each client sees only their own project, and that site managers can post to the projects they run but not see the office's cost figures. Mythex scopes each query to the signed-in user, so a client cannot open another job by changing the address in the browser. If architects or surveyors need read access to one project, ask for a guest role too.

Clients: their own project only
Site managers: post photos and notes
Office: everything, including costs

A prompt to start from

Build a client portal for a construction company. Each client logs in and sees only their project: phase timeline with planned and actual dates, progress photos per phase, drawings and certificates, a stage payment schedule with invoices, and variations with description and price that they approve or reject. Site managers can upload photos and notes from a phone for their own projects. The office sees all projects and costs. Use a database with per-user access.

Questions

Can each client see only their own project?

Yes. State it in the prompt and Mythex scopes every page and query to the signed-in client. Staff roles can see more, and you decide what each role can view or change.

Can clients approve variations in the portal?

Yes. Each variation has a price and an approve or reject action, with the date and the client's name saved. You can ask for approved variations to be added to the next invoice automatically.

Can site managers upload photos from site?

The portal works in a phone browser, so a site manager can take and upload photos straight into the right project and phase. Files are kept in the project's storage.

Do I need to know how to code?

No. You describe the portal in plain language, check it in the live preview, and change it by chatting.

Can the portal be a phone app?

On Pro, Mythex can turn the published portal into Android and iPhone apps that open your published app, so clients can install it. Every time you publish, the apps show the update.
